Fort Rosalie, built by the French in 1716 in the Natchez homeland, became the region’s main military, trading, and governing center and the nucleus of the town that became Natchez. Its construction followed the First Natchez War and relied on labor and materials compelled from the Natchez. As French settlement spread, tensions deepened until the Natchez revolt of November 29, 1729, when fighters captured the fort and devastated the French settlement. French and Choctaw forces retook the ruined post, and continued campaigns shattered the Natchez as a unified political nation. Later held by Britain, Spain, and the United States, the site reflects both shifting imperial control and the violence of colonial expansion.
